Low FODMAP Diet for IBS: List of Foods to Eat and Avoid

FODMAP foods for IBS, definition, and facts

A low FODMAP dietary plan can help ease IBS symptoms.

FODMAP stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols, which are short-chain carbohydrates and sugar alcohols that are poorly absorbed by the body, resulting in abdominal pain and bloating.
FODMAPs occur in some foods naturally or as additives.
If you eat a lot of these foods you may have symptoms and signs like:
- Gas
- Pain
- Bloating
- Abdominal distention
- Abdominal pain
- Diarrhea
A list of examples of certain foods and drinks to avoid on a low FODMAP diet are some vegetables and fruits, beans, lentils, wheat, dairy products with lactose, high fructose corn syrup, and artificial sweeteners.
A list of examples of foods and drinks to eat on a diet are certain vegetables and fruits, lactose-free dairy, hard cheeses, meat, fish, chicken, eggs, soy, rice, oats, quinoa, non-dairy milk, and small servings of nuts and seeds.
This diet cuts out many common foods that may contain high FODMAP foods. They are eliminated or severely limited for 3-8 weeks, then gradually reintroduced into a low-FODMAP diet to see if they cause symptoms (elimination diet). It is not meant to be a permanent solution because it is very restrictive, but it may work well enough to be a treatment for people with gastrointestinal (GI) problems.
This type of dietary meal plan often is used to help with digestive symptoms from many different conditions, including, irritable bowel syndrome (IBS), small intestinal bacterial overgrowth (SIBO), and other functional GI disorders.

What are FODMAPs?

FODMAPs are short-chain carbohydrates and sugar alcohols that are poorly digested by the body. They ferment in the large intestine (bowel) during digestion, drawing in water and producing carbon dioxide, hydrogen, and methane gas that causes the intestine to expand. This causes GI symptoms such as bloating and pain that are common in disorders like IBS.

FODMAPs are in some foods naturally or as additives. They include fructose (in fruits and vegetables), fructans (like fructose, found in some vegetables and grains), lactose (dairy), galactans (legumes), and polyols (artificial sweeteners).

These foods are not necessarily unhealthy products. Some of them contain fructans, inulin, and galactooligosaccharides (GOS), which are healthy prebiotics that helps stimulate the growth of beneficial gut bacteria. Many of them are otherwise good for you, but in certain people, eating or drinking them causes gastrointestinal symptoms.

What is a low FODMAP diet?

A low FODMAP diet cuts out many common products that contain certain foods. The principle behind the diet is to give the gut a chance to heal, especially if you have GI problems like IBS. People with GI disorders may use this diet as part of their treatment.

This diet may be difficult to follow, and it is advisable to contact your health care professional or a dietitian to make sure that you are on the right track and getting enough dietary nutrients that you can consume.

Will a low FODMAP diet help IBS or other diseases?

Low FODMAP diets are often used to help with digestive problems from many different conditions, including IBS.
These foods cause irritable bowel syndrome, but they also may aggravate IBS symptoms. A low FODMAP diet often is recommended for IBS treatment.
Small intestinal bacterial overgrowth (SIBO)
Functional GI disorders other than IBS

Experts believe that a meal plan that includes low FODMAPs also may help ease symptoms from other health conditions, such as:

Autoimmune diseases:
Fibromyalgia
Migraines triggered by eating certain products

After your doctor makes the diagnosis of your bowel disease or syndrome, (for example, IBS, IBD, or microscopic colitis), he or she may suggest a low FODMAP diet.

Symptoms and signs that you may be eating too many high FODMAP foods

FODMAPs are not absorbed well in the small intestine. They increase the amount of fluid in the large intestine (bowel) and they produce more gas.

Symptoms and signs that suggest you may be eating products high in these short chain carbohydrates are:

Gas
Pain
Bloating
Abdominal distention
Abdominal pain
Diarrhea (similar to IBS symptoms)
A feeling of fullness after eating or drinking only a small amount of food or liquid

A diet low in FODMAPs may help relieve these problems, particularly in people with IBS.

What is a FODMAP elimination diet?

This diet consists of severely restricting or eliminating those particular foods and drinks, but only for a short period of time because it may not meet all the nutritional dietary requirements you need. It can be very restrictive and it is not recommended as a permanent diet.
This meal plan may not provide any benefits for healthy people, and because it restricts many healthy foods it should only be tried if medically necessary and prescribed by your doctor or other health care professional.
For 3-8 weeks, foods and drinks that contain FODMAPs are limited or avoided. After that, individual foods can be introduced back into the diet, one at a time, to see whether that particular food or drink causes symptoms. If it does, you know you need to avoid that type of product. If no symptoms occur after consuming a particular food or drink for a week, it may be considered safe to continue to eat.
